A Contribution to New Technologies and Architectures Evaluation for Automotive Electrical Systems 2004-01-3419

The purpose of this work is to present the main aspects related to the new technologies and electrical architectures applicable to automotive vehicles, analyzing their technical characteristics before the current electrical systems. In particular, emphasis is given to a comparison between the application of 36V/42V electrical system, in direct current (DC), and 12V/14V DC electrical system. A literature review about the mentioned subject is presented.

The technical characteristics of the architectures considered for the implementation of that electrical system, proposed in the available literature, are presented, and the different point of views, related to the adoption of this new technology, are considered during the development of this work.

The analysis of those architectures considers merit indexes, defined according to specific criterions suggested in this work, and the application of an assessment methodology, allowing, therefore, a conclusive presentation and discussion of the final compendium of this analysis.
